EVALUATION OF SOME QUALITY PARAMETERS OF POPULAR POTATO SNACKS

S u m m a r y

The results of evaluation some physical and textural parameters of popular potato snacks are presented in the paper. Quality parameters were performed for 5 types of snacks with different raw materials used and final shape. The moisture content, bulk density, durability, water absorption index, chosen texture parameters (hardness, breaking strength) and sensory evaluation of snacks were tested.

The results of investigations for all tested products contained in ranges for this type of snacks cited in the literature. The best characteristics were performed for three-dimensional ‘Twistos 3D’ snacks and low acceptability was occurred for natural potato snacks. The sensory evaluation results were similar to instrumental measurement results, especially in the aspect of texture parameters.
